Interfacing 433MHz Transmitter And Receiver Modules With Arduino UNO

Wireless Communication: Interfacing 433MHz Transmitter and Receiver Modules with Arduino UNO

Harsh Sehgal 0 Comments

A 433MHz transmitter and receiver pair uses Amplitude Shift Keying (ASK) modulation to transmit and receive data wirelessly. The transmitter modulates a 433MHz carrier wave with the data signal using an ASK modulator, and transmits the modulated signal through an antenna. The receiver picks up the transmitted signal with an antenna, filters out unwanted...
